# Icons
A single control sets the line weight of every SVG icon in the theme — cart, search, account, arrows, and more — keeping them consistent across the store.
***
## Icon thickness
Adjusts the stroke weight of all icons at once, from **100%** (thin and refined) to **200%** (bold and assertive) — default **150%**. For a cohesive look, match it to your type: pair thinner icons with light fonts, heavier icons with bold headings.
